6020A
General description
The bi-amplified GENELEC 6020A is an extreme-
ly compact two way active loudspeaker designed
for home theaters and multimedia applications.
As an active loudspeaker, it contains drivers,
power amplifiers, active crossover filters and pro-
tection circuitry. The MDE™ (Minimum Diffraction
Enclosure™) loudspeaker enclosure is made of
die-cast aluminium and shaped to reduce edge
diffraction. Combined with the advanced Direc-
tivity Control Waveguide
TM
(DCW
TM
), this design
provides excellent frequency balance in difficult
acoustic environments. If necessary, the bass re-
sponse of the 6020A’s can be extended with a
Genelec 5050A subwoofer.
Positioning the loudspeaker
Each 6020A is supplied with an integrated am-
plifier unit, mains cable and an operating man-
ual. After unpacking, place the loudspeaker in
its required listening position, taking note of the
line of the acoustic axis. The axes of all loud-
speakers should converge at ear height at the
listening position (see Figures 1 and 2).
Connections
Before connecting up, ensure that the volume
control potentiometer on the front panel is turned
fully counter-clockwise to the stand-by setting.
Connect the loudspeaker to an earthed mains
connection with the supplied mains cable. Never
connect the loudspeaker to an unearthed mains
supply or using an unearthed mains cable.
The 6020A has two parallel 10 kOhm au-
dio input connectors: a balanced XLR and an
unbalanced RCA. For longer cable connection
lengths (>10 m or >30 ft) a balanced line con-
nection is recommended as it offers better im-
munity to external interference. However, the
RCA connection method is more commonly
available and usually works as well for shorter
connection lengths in less electrically noisy
environments. Do not use both inputs at the
same time. Consult your Genelec dealer for the
choice of signal cables. Once the connections
have been made, the loudspeakers are ready
to be switched on.
Volume control, Autostart and
stand-by switching
The input sensitivity of the loudspeakers can be
matched to the output of the preamp/proces-
sor by adjusting the volume control on the front
panel. When the volume control knob is turned
fully counter-clockwise, the 6020A goes into
stand-by mode. The loudspeaker can be left in
stand-by mode whenever it is not used, how-
ever, it is only completely disconnected from the
mains power when the mains cable is discon-
nected.
The 6020A is also equipped with a signal-
sensing Autostart function for automatic switch-
ing between “on and “stand-by” modes. Auto-
start is activated by turning switch 1 (AUTO-
START) on the back panel to ON”. Autostart
turns the amplifier to stand-by mode if there is
no signal present for about 30 minutes. When
the signal returns the amplifier switches on im-
mediately and the loudspeaker functions nor-
mally.
Setting the tone controls
The frequency response of the Genelec 6020A
can be adjusted to match the acoustic environ-
ment by setting the tone control switches on
the rear panel. The controls are “Treble Tilt” and

“Bass Tilt”. An acoustic measuring system such
as WinMLS or comparable is recommended for
analyzing the effects of the adjustments, howev-
er, careful listening with suitable test recordings
can also lead to good results if a test system
is not available. Table 1 above shows some ex-
amples of typical settings in various situations.
Figure 4 shows the effect of the controls on the
anechoic response.
Treble Tilt
Treble Tilt control (switch 2) attenuates the
treble response of the loudspeaker at frequen-
cies above 5 kHz by 2 dB, which can be used
for smoothening down an excessively bright
sounding system.
Bass Tilt
Bass Tilt control offers three attenuation levels
for the bass response of the loudspeaker below
2 kHz, usually necessary when the loudspeak-
ers are placed near a wall or other room bound-
aries. The attenuation levels are -2 dB (switch
3 “ON”), -4 dB (switch 4 “ON”) and -6 dB (both
switches “ON”).
The factory setting for all tone controls is “OFF”
to give a flat anechoic response. Always start
adjustment by setting all switches to “OFF” po-
sition. Measure or listen systematically through
the different combinations of settings to find the
best frequency balance.
Mounting considerations
Align the loudspeakers correctly
Always place the loudspeakers so that their
acoustic axes (see figure 1) are aimed towards
the listening position. Only vertical placement is
preferred, as it minimises acoustical cancella-
tion problems around the crossover frequency.
Maintain symmetry
Check that the loudspeakers are placed sym-
metrically and at an equal distance from the
listening position. If possible, place the system
so that the listening position is on the center-
line of the room and the loudspeakers are
placed at an equal distance from the centerline.
Minimise reflections
Acoustic reflections from objects close to the
loudspeakers like desks, cabinets, computer
monitors etc. can cause unwanted colouration
blurring of the sound image. These can be mini-
mised by placing the loudspeaker clear of re-
flective surfaces.

Minimum clearances
Sufficient cooling for the amplifier and function-
ing of the reflex port must be ensured if the
loudspeaker is installed in a restricted space
such as a cabinet or integrated into a wall
structure. The surroundings of the loudspeak-
er must always be open to the listening room
with a minimum clearance of 5 centimeters (2”)
behind, above and on both sides of the loud-
speaker. The space adjacent to the amplifier
must either be ventilated or sufficiently large to
dissipate heat so that the ambient temperature
does not rise above 35 degrees Celsius (95°F)
Mounting options
The 6020A offers several mounting options:
The Iso-Pod (Isolation Positioner/Decou-
pler™) vibration insulating table stand allows
tilting the loudspeaker for correct alignment
of the acoustic axis. On the base of the loud-
speaker is a 3/8” UNC threaded hole compat-
ible with a standard microphone stand. On the
rear there are two M6x10 mm threaded holes
for Omnimount
®
size 20.5 brackets or the key-
hole wall mount adapter provided with the loud-
speaker.
Maintenance
No user serviceable parts are to be found within
the amplifier unit. Any maintenance or repair of
the 6020A unit should only be undertaken by
qualified service personnel.
Safety considerations
Although the 6020A has been designed in ac-
cordance with international safety standards,
the following warnings and cautions should
be observed to ensure safe operation and to
maintain the loudspeaker under safe operating
conditions:
Servicing and adjustment must only be
performed by qualified service personnel.
The loudspeaker must not be opened.
Do not use this product with an unearthed
mains cable or an unearthed mains
connection as this may compromise
electrical safety.
Do not expose the loudspeaker to water or
moisture. Do not place any objects filled with
liquid, such as vases on the loudspeaker or
near it.
This loudspeaker is capable of producing
sound pressure levels in excess of 85 dB,
which may cause permanent hearing
damage.
Free flow of air behind the loudspeaker is
necessary to maintain sufficient cooling.
Do not obstruct airflow around the
loudspeaker.
Note that the amplifier is not completely
disconnected from the AC mains service
unless the mains power cord is removed
from the amplifier or the mains outlet.
